Introduction to Virtual Reality
Virtual reality is composed of an interactive computer simulation, which senses the user’s state and operation and replaces or augments sensory feedback information to one or more senses in a way that the user gets a sense of being immersed in the simulation (virtual environment) . Thus, it is possible to identify four key elements of virtual reality: virtual environment, sensory feedback (in response to user activity), interactivity and immersion.
